I just purchased Apple AirPort Express Base Station with 802.11n and AirTunes. I have a comcast cable modem. I took the ethernet cable from my mac pro and plugged it into the airport express. I then tried to install the airport utility cd, but it says its incompatible with my version of leopard. Is there a way to bypass this without using the disc. All im trying to do is setup a wireless network and I have no idea what the heck I'm doing. If anyone can help, it would be greatly appreciated. Thank you kindly.
